Emojis are not working in commit messages in pipelines page

Summary

If you write a commit message with emoji (something like 💥, for example), the emoji is correctly show from the "repository" page, but not from "pipelines" page.

Steps to reproduce

  • Commit some file to your repository, and use a emoji in the commit message (:boom:, for example)
  • Push commit to the server, and go to the "pipeline" page (%{project_path}/pipelines)
  • The commit message show as :boom: instead 💥

What is the current bug behavior?

Just a visual issue, is not a critical bug... but it's strange because in other pages the emojis are interpreted correctly.

What is the expected correct behavior?

The same behaviour like the rest of the pages with "commit messages", for example in %{project_path}/tree/master.

Relevant logs and/or screenshots

Correct behaviour:

Wrong behaviour:
